I have a Scantronic 9448+ panel and have just fitted a GardTes Novagard GA external sounder as some clown had stolen the cover of the prevoius sounder.

I have fitted the sounder as per instructions but when I power the system up and reset the alarm, the internal sounder stops but the external sounder does not.

The sounder is in Standard Mode.

Connections are:

Scantronic Novagard

0V 0V

+12V +12V

Bell S-

TR TMPR

STR STR-

TMPV jumpered to 0V

Any ideas?

P.S. I am an alarm novice but a qualified electrician

what voltage reading do you get between 12v and TR at the panel end ?

so your doomed then

i'd bet your tamper switches on the siren are not adjusted properly, if they are you need to break it down to see where the siren is being driven to sound from.

with a meter find out if a 'hold off' voltage is reaching the siren, or if the panel is 'driving' it from 'Bell-'.

you need to bend the lever a little bit

and short 0V to set too

What is it with Gardtec and having to put little bits of wire, capacitors, resistors etc in to make them work properly I like the stuff but christ...

is annoying, but they are fairly quick imo to put it right once they notice a problem.

given how long the known bugs on other kit have been in existence, like XM panels that can't recover from a power down if the battery is flat 98's dropping their programming , have a look at the problems the tex panels in the forums have, and gardtec seems still to be very good gear at a fair price.

gardtec seem to respond very well to feedback and problem discovered..... imo
